There are numerous potential causes of hair loss, both genetic and environmental. One of the most common causes of hair loss is androgenetic alopecia, also known as male or female pattern baldness. This type of hair loss is hereditary and caused by sensitivity of hair follicles to dihydrotestosterone (DHT), a byproduct of the male sex hormone testosterone. DHT binds to receptors on hair follicles located at the top and front of the scalp, gradually making them smaller over time until they produce finer hairs or no hair growth at all.
Other potential causes of hair loss include stress, major illness, crash diets or rapid weight loss, medications, thyroid disorders, chemotherapy treatments for cancer, pregnancy, menopause, and other Hair loss treatment , hormonal imbalances or changes. Scalp infections like fungal infections or ringworm can also result in temporary hair shedding or loss of patches of hair. Trichotillomania, the compulsive urge to pull out one's hair, is a psychological condition that may lead to noticeable hair loss as well.
Medical Treatments for Hair Loss
There are several FDA-approved prescription medications that can help slow or stop hair loss and promote regrowth for those with androgenetic alopecia. Finasteride and dutasteride work by blocking the conversion of testosterone to DHT, the hormone believed to be primarily responsible for hereditary hair loss. Both are available in pill form and must be taken daily. Their effectiveness in regrowing hair varies but they can help maintain the hair many patients still have.
Minoxidil, sold under the brand name Rogaine, is a topical liquid or foam applied directly to the scalp. It works to regenerate follicles and reactivate dormant bulbs to grow new, thinner hairs. Results aren't always dramatic but the medication can help slow further loss or regrow some hair when used indefinitely. An oral minoxidil treatment called Loniten has recently been approved as well.
Low-level laser treatments deliver targeted beams of light to the scalp to stimulate follicles. Several sessions over a number of weeks may help thicken existing hairs and produce new small hairs. Platelet rich plasma injections use a patient's own blood plasma, rich in platelets and growth factors, to inject directly into balding areas in hopes of rejuvenating follicles.
Hair transplants are a surgical option that involves grafting hair follicles from the back and sides of the scalp, where DHT sensitivity is lower, to balding areas. Both follicular unit strip surgery and follicular unit extraction are popular techniques that result in a natural appearance when done by a skilled surgeon. Transplants do require multiple procedures for best results.
Natural and Alternative Treatments
For those looking for more natural options, there are several alternative treatments thought to potentially aid hair loss when used regularly. Saw palmetto is an herb containing compounds that may inhibit 5-alpha reductase, the enzyme that converts testosterone to DHT. Topical applications of essential oils like rosemary, peppermint and cedarwood that are thought to increase circulation have gained popularity as well. Some promote hair growth when massaged into the scalp.
Vitamin supplements aimed at supporting hair are another option some try. Biotin, collagen, keratin, iron, vitamin D, and certain B vitamins like B6, B12 and folate play nutritional roles in healthy hair and may theoretically help treat hair shedding when deficient. However, more research is still needed on their ability to truly regrow hair. Other natural remedies include onion juice, garlic, ginger and horsetail teas applied topically. Limited studies show compounds in these plants possess properties that could aid follicles but results are mixed.
Stress management through yoga, meditation, massage or other relaxation techniques may be helpful too. Reducing stress on both the body and mind could benefit overall hair health over the long term for some, even if not curing the underlying cause itself. Maintaining a healthy, balanced diet with all essential vitamins, minerals, proteins and fatty acids is always advised as strong general support for hair as well.
Risks and Costs of Treatments
Prescription drugs like finasteride and minoxidil are generally very safe for most users but can cause side effects in some individuals like irregular heartbeats, erectile dysfunction or decreased libido. Laser hair therapies pose minimal risks but multiple treatments can become costly, normally in the hundreds to low thousands of dollars range. Hair transplants require anesthesia and surgical skill so inherent surgical risks apply, plus the procedure is usually the most expensive option, averaging anywhere from $4,000 to $15,000 or more depending on the extent of needed grafts.
Natural remedies have fewer side effects risks but most also lack definitive scientific evidence of ability to truly regrow hair quantity and quality on their own. Some natural treatments are inexpensive, while others like supplements or topical essential oils can still accumulate costs when used over long periods. Patient satisfaction also depends highly on individual factors like severity or cause of hair loss and expectations of treatment outcomes. Overall education on options as well as consulting medical experts is advised before committing significant time and money into any hair loss treatment regimen.
While hair loss itself can affect self-esteem and quality of life for many, selecting the treatment approach that best suits an individual requires considering variables such as hair loss etiology and progression, expectations, safety profile, convenience and affordability. Both prescription medications and surgical hair restoration can notably improve hair fullness when used properly for androgenetic alopecia. Natural products and alternative therapies may also provide some benefits for certain patients but with less guarantee. Overall maintenance of general scalp health remains important as well. The decision largely depends on weighing these and other personal factors with a qualified medical professional's guidance.
